[−][src]Struct rusoto_waf_regional::SizeConstraint
Specifies a constraint on the size of a part of the web request. AWS WAF uses the Size
, ComparisonOperator
, and FieldToMatch
to build an expression in the form of "Size
ComparisonOperator
size in bytes of FieldToMatch
". If that expression is true, the SizeConstraint
is considered to match.
Fields
comparison_operator: String
The type of comparison you want AWS WAF to perform. AWS WAF uses this in combination with the provided Size
and FieldToMatch
to build an expression in the form of "Size
ComparisonOperator
size in bytes of FieldToMatch
". If that expression is true, the SizeConstraint
is considered to match.
EQ: Used to test if the Size
is equal to the size of the FieldToMatch
NE: Used to test if the Size
is not equal to the size of the FieldToMatch
LE: Used to test if the Size
is less than or equal to the size of the FieldToMatch
LT: Used to test if the Size
is strictly less than the size of the FieldToMatch
GE: Used to test if the Size
is greater than or equal to the size of the FieldToMatch
GT: Used to test if the Size
is strictly greater than the size of the FieldToMatch
field_to_match: FieldToMatch
Specifies where in a web request to look for the size constraint.
size: i64
The size in bytes that you want AWS WAF to compare against the size of the specified FieldToMatch
. AWS WAF uses this in combination with ComparisonOperator
and FieldToMatch
to build an expression in the form of "Size
ComparisonOperator
size in bytes of FieldToMatch
". If that expression is true, the SizeConstraint
is considered to match.
Valid values for size are 0 - 21474836480 bytes (0 - 20 GB).
If you specify URI
for the value of Type
, the / in the URI counts as one character. For example, the URI /logo.jpg
is nine characters long.
text_transformation: String
Text transformations eliminate some of the unusual formatting that attackers use in web requests in an effort to bypass AWS WAF. If you specify a transformation, AWS WAF performs the transformation on FieldToMatch
before inspecting a request for a match.
Note that if you choose BODY
for the value of Type
, you must choose NONE
for TextTransformation
because CloudFront forwards only the first 8192 bytes for inspection.
NONE
Specify NONE
if you don't want to perform any text transformations.
CMD_LINE
When you're concerned that attackers are injecting an operating system command line command and using unusual formatting to disguise some or all of the command, use this option to perform the following transformations:
-
Delete the following characters: \ " ' ^
-
Delete spaces before the following characters: / (
-
Replace the following characters with a space: , ;
-
Replace multiple spaces with one space
-
Convert uppercase letters (A-Z) to lowercase (a-z)
COMPRESS_WHITE_SPACE
Use this option to replace the following characters with a space character (decimal 32):
-
\f, formfeed, decimal 12
-
\t, tab, decimal 9
-
\n, newline, decimal 10
-
\r, carriage return, decimal 13
-
\v, vertical tab, decimal 11
-
non-breaking space, decimal 160
COMPRESS_WHITE_SPACE
also replaces multiple spaces with one space.
HTML_ENTITY_DECODE
Use this option to replace HTML-encoded characters with unencoded characters. HTML_ENTITY_DECODE
performs the following operations:
-
Replaces
(ampersand)quot;
with"
-
Replaces
(ampersand)nbsp;
with a non-breaking space, decimal 160 -
Replaces
(ampersand)lt;
with a "less than" symbol -
Replaces
(ampersand)gt;
with>
-
Replaces characters that are represented in hexadecimal format,
(ampersand)#xhhhh;
, with the corresponding characters -
Replaces characters that are represented in decimal format,
(ampersand)#nnnn;
, with the corresponding characters
LOWERCASE
Use this option to convert uppercase letters (A-Z) to lowercase (a-z).
URL_DECODE
Use this option to decode a URL-encoded value.
